Air Bag Readiness Light

There is an air bag readiness light on the instrument
panel, which shows the air bag symbol. The system
checks the air bag's electrical system for malfunctions.
The light tells you if there is an electrical problem.
The system check includes the air bag sensors, the air
bag modules, the wiring and the crash sensing and
diagnostic module. For more information on the air bag
system, see Air Bag Systems on page 1-49.
If the air bag readiness light stays on after you start
the vehicle or comes on when you are driving, your air
bag system may not work properly. Have your vehicle
serviced right away.
This light will come on
when you start your
vehicle, and it will flash
for a few seconds.
Then the light should
go out. This means the
system is ready.
